%X Alpha-1 antitrypsin (A1A) deficiency is an underdiagnosed risk factor for Chronic
Obstructive Pulmonary Disease (COPD), as well as liver disease. Among the A1A deficient
population, only an estimated 15% are diagnosed. The reason may be due to its nearly
indistinguishable presentation to COPD from other etiologies. We conducted a retrospective,
cross-sectional study to determine the prevalence of A1A genotypes in patients presenting
with airway obstruction symptoms.
